SEGMENTAL HACK- Specification of Letters Patent.

tatenteol April 10, 1906 Application and January 2, 1906. Serial No. 294,190.

To all whom 1125 may concern:

Be it knownthat I, WILLIAM H. Voss, a citizen of the United States, and a resident of Davenport, in the county of Scott and State of Iowa, have invented certain new and useful Improvements in Segmental Racks, of which the following is a clear, full, and exact description. I V V My invention relates to'the construction of the segmental racks used in mechanical movements for the purpose of operating washin machines, churns, &c. While it is particu arly adapted for use in connection with a washing-machine of the type illustrated and described in United States Letters Patent No. 664,911, granted to me January 1', 1901, it may also be employed in other movements-such, for example, as that set forth. in United States Letters Patent No.

750,136, granted to me January 19, 1904.

Theobject of my invention is to provide a simple yet effective means for connecting the reversing horns or crescents, upon which the greatest strain and wear of mechanism of this kind comes, securely to the segmental rack, so that the possibility of the bolts used to fasten it in place will not shear and in case of it working loose it will not get out of cooperative relation with the rest of the 1nechanism and can be easily and quickly tightened and when broken can be readily relaced. This I accomplish in the manner iereinafter more fully described and as particularly pointed out in the claims.

In the drawings, Figure 1 is a top plan view of my invention. Fig. 2 is a side elevation thereof. Fig. 3 is a transvertical section taken on dotted line 3 3 of Fig. 2 looking in the direction indicated by the arrows. Fig. 4 is a view of a portion of the rack, showing in detail the boss for attaching the guideblock; and Fig. 5 is a detail view showing the construction of said guide-block.

Referring to the drawings, A represents a suitable annulus, preferably constructed as shown in the drawings and provided with a central opening throu 'h which the stirrer or rotary reciprocal shalt extends. The perimeter of this annulus is surrournled by a vertically-disposed flange B, that extends around, say, three-fifths of the circumference thereof and has its ends b rounded. Projecting radially from the outer face of this flange is a segmental rack C, comprising a series' of equidistant teeth 0, that have their outer ends connected by a surrounding rimfOIITl a blunt apex E.

c. The edge of the annulus A between the rounded ends of the flange B is preferably cut away at b b, as shown in Fig. 1 of the dnwings, and midway between the ends of theflange said edge is projected outward to y Cast upon this apex E is a bracket comprisirg a verticallyelor;-

gated plate 0, preferably rectangular in shape and havir g suitable v(. .rtically-elongatcdslots or bolt-holes a c cut in its upper and lower edges.

All of the parts above described are preferably made or cast in one piece with the anrulus, although it is quite obvious that the same could be cast in several pieces, if found more desirable.

The plate c is adapted to support the removable revers'ing-plate that is cast in the shape shown in Fig. 5 of the drawings. and which is secured thereto by means of bolts or rivetsff. This reversing-plate has its vertically-disposed side edges l-l ll curved to conform to a segment of a circle struck from the center of the TOUl'KlGd. ends of the flange B andis of such dimensions that when in proper position a semicircular guide channel is formed between its side edges and the ends of said flange. It is cast in one piece of metal, and it provided with a centrally-located socket or depressed seat 9 in its inner surface of such d cpth and. dimensions as to fit over and surround the plate c of the bracket. if desired, this seat g may be made by bulging the central portion of the reversing-plate outward, although it is obvious said plate maybe made thicker at this point, if desired. In either event bolt-holes g g are made for the bolts or rivetsff, which latter have their headed ends on the inside of the bracketplate a and have their shafts extend through the slots c e. and through holes g g and are provided with nuts h h on their outer ends. The squared portions of the barrels of the bolts rest in the slots 6 e, which latter are made deep enough so that when securing the reversing-plate to the bracket any slight variation in the shape of the bracket or reversing-plate due to defective castings will not prevent the proper assembling of the parts.

What I claim as new is -1. In a segmental rack for mechanical movementsa bracketbetween the ends of the rack having suitable bolt-openings therein; and a reversing-plate having a depressed seat' in its inner surface into which said bracket is fitted, and suitable bolts extending through the openings in said bracket and through said reversing-plate for fastening the latter to the former.

2. In a segmental rack for mechanical movements a bracket between the ends of the rack; a reversingplate having a depressed seat in its inner surface into which said bracket is fitted; and means for securing saidreversing-plate to said bracket.

3. In a segmental rack for mechanical movements a bracket between the ends of the rack; a reversing-plate having a depressed seat in its inner surface into which said bracket is fitted; and means assing through said bracket and reversing-p ate for securing the latter to the former.

.4. In a segmental rack for mechanical movements a bracket consisting of a vertically-disposed rectangular plate located be tween the ends of the rack; a reversing-plate having a depressed seat in its inner surface into which said bracket is fitted; and means for securing said reversing plate to said bracket.

5. In a segmental rack for mechanical movements a bracket between the ends of the rack; a reversing-plate having a depressed seat in its inner surface correspondmg inshape to the contour of said bracket into' 'which the latter is fitted; and means for securing said reversing-plate to said bracket.

6. In a segmental rack for mechanical movements a bracket consisting of a vertically-disposed rectangular plate located midway between the ends of the rack; a reversing-plate having a depressed seat in its inner 'slizas surface corresponding in shape to the contour of said plate into which the latter is fitted; and means for securing said reversing plate to said rectangular plate.

7. In a segmental rack for mechanical movements a bracket consistin of a vertically-disposed rectangularplate located midway between the ends of the rack; areversing-plate having a depressed seat in its inner surface corresponding in shape to the contour of said plate into which the latter'is fitted; and means passing through said bracket and reversing-plate for securing the latter to the former.

8. In a segmental rack for'mechanical' movements a bracket consisting of a vertl cally-disposed' rectangular plate located be tween the ends of the rack and having suitable bolt-o enings therein; a reversing-plate having a epressed seat in its inner surface having bolt-openings therein registering with those in said rectangular plate, said seat corresponding in shape to the contour of said rectangular plate into which the latter is fitted; and suitable bolts extending through the openings in said bracket and said reversin'g-plate for fastening the latter to the former.

In testimony whereof I have hereunto set myv hand this 8th day of December,- A. D. 1905. i t
